Dünfus lies in a hollow in the Eifel south of the Brohlbach, west of Brohl and Forst.

The overlordship was held by the Electorate of Trier until 1794 when the area was occupied by French Revolutionary troops.

In 1815 Dünfus was assigned to the Kingdom of Prussia at the Congress of Vienna and was made part of the Prussian Bürgermeisterei (“Mayoralty”) of Karden.

The ash urn is an archaeological artefact that was found in 1929 on the Häckelsberg, a local mountain, during excavation work.

Drawn from their arms is the charge in the third quarter, the bend dancetty (slanted zigzag stripe).
